Outputs of the leaf cohort model in two contrasted K fertilisation regimes. The K content present in each individual leaf of the cohort is represented through the lifespan of a cohort (x axis) for the different cohort created along the first 60 months of the rotation (a, c). The symptom area proportion for each leaf of the cohort is also represented (b, d). Top subplots (a, b) were simulated in +K conditions, while bottom subplots were oK simulations (c, d).

The extent of the potassium (K) limitation of forest productivity is probably more widespread than previously thought, and K limitation could influence the response of forests to future global changes. To understand the effects of K limitation on forest primary production, we have developed the first ecophysiological model simulating the K cycle an...

... This was necessary since CASTANEA was not originately simulating the hydraulic continuum, and the assumption of a fixed root depth made by CASTANEA was not valid in the studied system. Details on the development of the CASTANEA-MAESPA coupled model can be found in (Cornut et al., 2022a;Cornut et al., 2022b). A schematic overview of the model is given in Figure 1. ...
... Simulations were compared with measured biomasses for a five-year rotation. Notably, the CASTANEA-MAESPA model also simulates the K cycle, as described in (Cornut et al., 2022a) which also allowed to test the impact of rainfall reduction on biomass production under K omission. ...
